A) \[\{x\in R:x>0\}\]
B) \[\{x\in R:x\le 0\}\]
C) \[\{x\in R:0\le x\le 1\}\]
D) \[\{0,\,1\}\]
Correct Answer: D
Solution :
We have, \[f(x)=[2x]-2[x]\] For \[x=0,\,f(0)=[0]-2[0]=0\] For \[x=0.45,\,f(0.45)=[0.90]-2[0.45]\] \[=0-0=0\] For \[x=0.5,\,f(0.5)=[1.0]-2[0.5]\] \[=1-0=1\] For \[x=0.99,\,f(0.99)=[1.98]-2[0.99]\] \[=1-0=1\] So, the range of f is \[\{0,1\}\]You need to login to perform this action.
